BURNER son Lane's roza niacin FUEL.

Application filed February This invention relates to improvements infromthe incandescent mantle at the com paratively short part which isclosest to the incandescent mantle, the remaining parts of the vaporizertube which are farther distantfrom the incandescent mantle being lessheated, wherefrom results that the hydrocarbon is carbonized at theoverheated parts of the vaporizer tube.

In accordance with the invention the feeding from a point above thereservoir and the vaporizing are effected by single tube including alower portion which extends axially upwardh from above the reservoir inalignment ate bent port-ion and an upper offset'portion both the bentportion and the upper offset portion extending close to andsubstantially following the contour of the mantle. In priorconstructions having a similar external appearance the tube has servedas a housing for separate devices or is built up of a number of parts ordoes not extend axially from the reservoir and does not serve both afeeder and a vaporizer.

Bin embodiment of the invention is illustrated by way of example on theaccompanying drawings in which a table lamp ed with an invertedincandescent mantle is shown.

Lhe hollow foot 2) of the table lamp which as reservoir for thehydrocarbon q to be vaporized has a filling tube i for the liquid fuelclosed by a screw cap and a pump 1' designed to produce the requiredu-essure in the resermir. A hollow column a upwardly extending from thehollow foot 1) has a crown s which carries a lyre-shaped support in fora canopy n. The lamp shade w rests on. said canopy n. A tube extendingthrough said hollow column 8 serves to feed the liquid fuel from thereservoir 1) to the vaporizer tube A fixed on the upper end of tube j bymeans of an internally threaded sleeve u. The feeding and vaporizer tubeA comprises a lower portion a which forms the "extension of the tube y,a bent portion with the mantle, an intermediprovid 13, 1924, Serial No.692,504, andrin Germany February 22, 1923.

c and an upper oil's-ct portion (6 which is parallel to the lower branch0/ and the coil portion (0 forming an extension of the portion (i Aheating cup 7" serving to start the heating is mounted on the lowerbranch (6', said cup being filled with an easily vaporizingfueltspirit). The coiled portion a wound around tne arm 73 70" of themixing tube terminates in a nozzle (Z st nding opposite the upwardlyextending arm 76' of the U shaped mixing tube on the downwardly directedarm a of which the incandescent; mantle g is suspended with the aid of aporcelain ring 9. The arm 70 of the mixing tube traverses ney 0, acollar Z. of said arm 70 securing the mixing tube in its position, Thechimney 0 is carried by the support at through the intern'ie'diary of acasing having slits 'w. The vaporizer tube A the branch at of whichextends in axial direction from the column s, s is bent at a so that itsarm a is as close as possible to the cylindrical incandescent mantle gfor the longest possible extent. The liquid fuel which has been broughtunder pressure in the reservoir 29 by means of the pump 1' is forced upthrough the pipe j into the vaporizer tube A in which it is exposed tothe action of the heat radiating from the incandescent mantle g. Thelamp is lighted by ing cup As the fuel is strongly heated as soon as itenters into the branch (4 of the vaporizer A, the heating increasinggradually and remaining uniform for arather long extent, a carbonizingof the fuel on the strongly heated part of the vaporizer is avoided. andflows out as gas from the nozzle (Z into the mixing tube 70, 70 where itadinixes with the air, the mixture being burned in the invertedincandescent mantle g. I

By reason of the shape of the vaporizing tube the vaporizing tcmmratureattained with certainty, and any objectionable or detrim lital hightemperature is avoided. At the same time there are avoided all sharpedges, soldered parts, or parts otherwise joined which would complicatethe manufacturing, add to the expense, and cause unsightliness andobstruction of the tube. Furthermore the shape of the tube permitsaccessibility of the incandescent mantle and re I duce to a minimumshadows from the light.

I claim the bottom plate 0 of a chimthe flame produced in the heat,

The fuel is vaporized in tube A 1. A burner including a reservoir forliquid fuel, a tube extending upwardly from the reservoir, a vaporizingtube having its lower end secured to the said first mentioned tube andhaving a. nozzle at its upper end, an inverted U-shaped' mixing tubehaving one end disposed above said nozzle and the other end disposed inalinement with the first mentionedtube and provided with a;

mantle support, a canopy support, a chimney mounted on the canopysupport, 'seid mixing tube being supported fromsuid chin'iney, and :1loop portion formed in the vaporizing tube and encircling one leg of themixing tube and vaporizing tube including alower portion extendingaxially upwardlyfrom said reservoir in alignment with the mantle, an

intern'iediate bent portion and an upper ofts-et portion, both the bentportion and the upper oli'set portion extending close to andsubstantially following the contour of the mantle.

In t c, mony whereof I al'fix my slgneture.
